Download RULES FOR ACCENT MARKS IN SPANISH

RULES FOR ACCENT MARKS IN SPANISH: When are they used?
1. To distinguish meaning between two words that are spelled the same, but have
different meanings. Examples:
tu = your
tú = you (subject)
el = the
él = he
si = if
sí = yes
solo = alone
sólo = only
The following words have accent marks when they are used as question words:
¿Qué? = What?
¿Quién? / ¿De quién? = Who? / Whose?
¿Dónde? = Where?
¿Cuándo? = When?
¿Cuánto/a? = How much?
¿Cuántos/as = How many?
¿Cómo? = How?
¿Cuál? = Which?
2. To separate a diphthong (diptongo in Spanish), or the sound produced when a
strong vowel (a, e, o) and a weak vowel (i, u) would normally be combined into a
single sound or syllable. The accent is placed on the WEAK vowel to separate the
sounds. This is called 'hiato' in Spanish or 'hiatus' in English. Examples:
DIPHTHONG MAINTAINED: no accent mark
farmacia, historia, Mario, Ruiz, puede, prefiero, tiene, viene, continuo (adjective),
caigo (= I fall), oigo (= I hear), siento ( = I feel), diccionario, cuarto, escritorio
NOTE: It is possible to have an accent mark on a word with a diphthong, but it would
be used to indicate that the syllable with the diphthong is the stressed syllable and
breaks the rule for its 'group': -n, -s, vowel endings vs. consonant [except - n, -s] endings.
Example: suéter. This word ends in 'r', and therefore, according to the rule for words
in that group, it should stress the final syllable. (See next page). Since the next-to-last
syllable is stressed, it breaks the rule and requires an accent. The accent mark is placed
on the strong vowel of the diphthong to indicate that the stress falls on that syllable
and to maintain the two vowels as a diphthong (one sound).
HIATUS: DIPHTHONG SEPARATED with ACCENT MARK
día, librería, cafetería, biología, María, Raúl, continúo (verb), búho, caí (= I fell),
oí (= I heard), ríe (= He/ She laughs), tío/a

The next two groups, 3 and 4, give the rules for using accent marks when the word
breaks the stress rule that applies to the group it belongs to:
3. Palabras llanas (or graves). Words ending in a vowel, n, or s should stress the nextto-last syllable. If they do, they are called 'palabras llanas' and do not require an accent.
EXAMPLES of words that FOLLOW the rule for this group:
usted-es
a-bri-go
fal-da
su-da-de-ra
pre-cio***
som-bre-ro
bi-blio-te-ca
con-se-je-ro
im-per-me-a-ble
pro-fe-so-ra
es-tu-dian-te***
om-pu-ta-do-ra
***Note that the 'io' in the word precio is a diphthong, or a single sound, and hence a
single syllable, thus making 'pre-' the next-to-last syllable. The '-ia' in estudiante is also a
diphthong. These words therefore still follow the rule and need no accent.
Other examples: materia, residencia, historia, farmacia, edificio, diccionario, secretaria
Words with these endings (vowel, -n or -s) that stress the final syllable instead of the nextto-last syllable are called 'palabras agudas' and break the rule. They require an accent on
the stressed syllable to show that they break the rule.
EXAMPLES of words that DO NOT FOLLOW the rule for this group:
in-glés
*es-tá
es-táis
al-ma-cén
com-pu-ta-ción
a-diós
*es-tás
es-tán
vein-ti-dós
in-ves-ti-ga-ción
a-le-mán
vein-ti-trés
cin-tu-rón
* = When these words are conjugations of the verb estar, they require an accent mark because the final
syllable of the verb is stressed, as seen above: ¿Cómo está tu hermano? = How is your brother?
= When these words are demonstrative adjectives, they are stressed on the next-to-last syllable and
require no accent because they follow the rule in that case:
Quiero comprar esta mochila. = I want to buy this backpack.
= When these words are demonstrative pronouns, they require an accent mark to distinguish them from
the demonstrative adjectives: Quiero comprar éstas. = I want to buy these (ones).

4. Palabras agudas. Words ending in a consonant (except n, or s) should stress the
last syllable. If they do, they called 'palabras agudas' and require no accent.
EXAMPLES of WORDS that FOLLOW the rule for this group:
 NEARLY ALL verb infinitives follow this rule:
ha-blar
co-mer
vi-vir
ven-der
es-cri-bir
re-ga-te-ar
en-se-ñar
pre-gun-tar
bai-lar
en-ten-der
Here are some rare exceptions of infinitives with accent marks due to 'hiato':
sonreír (= to smile), oír (= to hear)]
Other examples of words that follow the rule for this group:
 pa-pel
pa-ra-sol
re-loj
us-ted
Or-tiz
tra-ba-ja-dor
es-pa-ñol
ac-ti-tud
li-ber-tad
Cha-pul-te-pec
Mu-ñoz
pro-fe-sor
Words with these endings (consonant except -n or -s) that stress the next-to-last syllable
instead of the last syllable are called 'palabras llanas' and break the rule. They require an
accent on the stressed syllable to show that they break the rule.
EXAMPLES of words that DO NOT FOLLOW the rule for this group:
lá-piz
ál-bum
ár-bol
dó-lar
Ló-pez
Her-nán-dez
Nú-ñez
5. Palabras esdrújulas: Words that have the stress on the third-to-last syllable are called
'esdrújulas.' ALL words that have the stress on the third-to-last syllable require an accent
on the stressed syllable:
a-é-re-o*
ma-te-má-ti-cas
bo-lí-gra-fo
es-tó-ma-go
sim-pá-ti-co
mé-di-co
mag-ní-fi-co
ma-trí-cu-la
ar-tí-cu-lo
úl-ti-ma
* Note that when strong vowels occur in succession, they are always pronounced as separate syllables.
Since all four vowels in this word are strong vowels, they are all pronounced separately and hence the
word also has 4 syllables.

6. Plural forms of nouns and adjectives.
THE PLURAL FORM OF WORDS ENDING IN A VOWEL, -N OR -S in SINGULAR:
A. Words ending in a vowel in the singular will not change in the plural form,
since they only add -s in the plural, and therefore do not add an extra syllable.
In other words, if they have an accent in the singular, they will have an accent in the
plural, and vice-versa. Examples:
NO ACCENT IN SINGULAR OR PLURAL:
ca-sa // ca-sas
ACCENT IN SINGULAR AND PLURAL: (due to being esdrújulas)
bo-lí-gra-fo // bo-lí-gra-fos
B. Words ending in -n or -s will add -es in the plural, and therefore will add an extra
syllable to the word. Whether they add or get rid of an accent in the plural form will
depend on the stressed syllable according to the rules for the group of words ending
in 'vowel, -n or -s', since in the plural they will all belong to that group. Examples:
ACCENT DISAPPEARS IN PLURAL: Nouns and adjectives ending in -n or -s that
stress the final syllable in the singular will lose the accent in the plural form:
 cin-tu-rón vs. cin-tu-ro-nes: The plural of the noun cinturón does not require an
accent because the added syllable means that the word then follows the rule.
 cor-tés vs. cor-te-ses (= courteous, polite): The plural of the adjective cortés does
not require an accent because the added syllable means that the word then follows the
rule.
ACCENT IS ADDED IN PLURAL: Nouns and adjectives ending in -n or -s that
stress the next-to-last syllable in the singular will add an accent in the plural form:
 ex-a-men vs. ex-á-me-nes: The plural of the noun examen requires an accent
because the stress is maintained on the syllable -a, but with an added syllable in the
plural, the word then breaks the stress rule and also becomes esdrújula.
 jo-ven vs. jó-ve-nes: The plural of the adjective joven requires an accent because
the stress is maintained on the syllable -jo, but with an added syllable in the plural, the
word then breaks the stress rule and also becomes esdrújula.

B. THE PLURAL FORM OF WORDS ENDING IN A CONSONANT EXCEPT -N or -S
IN THE SINGULAR:
Words in this group must add -es to the plural form, since all words ending in a consonant
in Spanish add -es to form the plural. This change does create any change in accent
marks: words in this group that have an accent in the singular will maintain their accent
in the plural. Words without an accent in the singular will not have an accent in the plural
form, either.
EXAMPLES:
ACCENT IN SINGULAR AND PLURAL:
 lá-piz // lá-pi-ces: The noun lápiz requires an accent in the singular and plural forms
because, in each case, it breaks the stress rule of the group it pertains to based on its ending.
(In its plural form, it is also an esdrújula and would automatically require an accent for
that reason.)
NO ACCENT IN SINGULAR OR PLURAL:
 pa-ra-sol // pa-ra-sol-es: The noun parasol does not require an accent in the singular
or plural because, in each case, it follows the stress rule of the group it pertains to based on
its ending.
